Logbook: September 7, 2003 Science Report / Cruise Summary
Our NeMO 2003 expedition has been a tremendous success. We came out here with a long list of things we wanted to do and not very much time to do them in. However, we were able to do almost everything we had planned, thanks to good weather and the hard work of the ship's crew, the ROPOS group, and the scientists on board. It is now 5 years since the 1998 eruption at Axial Volcano. After the dramatic changes we saw right after the eruption (new lava on the seafloor, new hydrothermal vents becoming established and colonized, and warm water and microbial blooms almost everywhere), we have documented a slow decline in hydrothermal systems in the eruption area since then. Some vents gradually declined in temperature while others stopped venting altogether. So before this expedition, we did not know if more, or perhaps even all of the sites that we had been monitoring would now be completely dead; the heat and chemicals from the 1998 eruption now completely dissipated. But that is not what we found. more...

Teacher's Report Bill Hanshumaker, Educator at Sea
The New Millennium Observatory (NeMO) was conceived in 1996 as a long-term study of the interactions between geology, chemistry, and biology on a dynamic part of the mid-ocean ridge system. Using state-of-the-art technology, NeMO continues to evolve. It has been wildly successful, not only with its scientific endeavors, but also in its educational outreach efforts. NeMO has touched the lives of educators, students and the general public. Each year, teachers are sent to sea with scientists on a research vessel to investigate Axial Volcano. Educators come from across the country, from New York to Oregon, and return to their hometowns with new knowledge and enthusiasm for ocean exploration. more...
